I'm a PhD student in PDOS, the Parallel and Distributed Operating Systems group at MIT, advised by Robert Morris and Eddie Kohler. My research interests are in distributed systems, particularly having to do with consistency and performance. I'm graduating soon and looking for opportunities in industry. Here is my CV.

Doppel. Doppel is an in-memory multicore transactional database designed to improve performance on workloads with many conflicting transactions. Doppel uses a technique called phase reconciliation; we take advantage of commutativity and executing transactions in explicit phases in order to increase concurrency. Doppel provides a dramatic performance improvement on highly conflicting workloads.
Pequod. Pequod is an in-memory distributed caching layer which can automatically materialize and update the results of simple joins. It simplifies programs which manually perform incremental updates to cached objects, like Twitter timelines.
Dixie. Dixie is a SQL query planner, optimizer, and executor which issues SQL queries written for one database over a database sharded and replicated over multiple servers. Dixie focuses on increasing inter-query parallel speedup and throughput by involving as few servers as possible in each query.
Projects and Writings
Reddit AMA. We did a Reddit AMA on being PhD students at MIT CSAIL. It made it to the Reddit front page and got over 4500 comments. We then wrote an article for Wired about the experience, and it was covered in Wonkette, The Dish, Business Insider, and BostonInno. Alexis Ohanian interviewed us about it for his podcast, Upvoted
Hearsay House. We designed and executed an art installation for the Reykjavik Arts Festival in May 2012. Hearsay House takes the narrative of a seminal meeting between Ronald Reagan and Mikhail Gorbachev in 1986, and subverts it to tell many different interesting stories. Visitors are invited to engage and participate in sensor setups in the Hofdi House. The data from that engagement is then transformed and visualized in the Reykjavik Arts Museum.
Hyperlinker. Hyperlinker is a tool for authors to modify the way they use hyperlinks in their text. Hyperlinker uses attributes in link tags to auto-generate information about the links, and lets the user toggle links on and off. Hyperlinker was inspired by reading lots of annoying blog posts where people link indiscriminately in ways that are hard to understand, and was done as a final project for MAS.S61.
Tubely. How do you decide what to watch when you get together with friends? Tubely aims to solve this problem using novel recommendation algorithms based on combining the preferences of individuals watching together in a group. We implemented Tubely as an interface to keep track of shows you're interested in, create playlists, get recommendations based on mood, and more. This was a final project for MAS.571.
